Objectives for Today’s meeting

• Review ‘As-is’ iGT process for MPRN creation, set up & initial Shipper registration

• Review Strawman processes• Agree requirements• Agree plan for next meeting

7Key aspect of current arrangements and possible changes with Nexus solution

• CSEP set up is a two stage process; – GT notifies Xoserve of CSEP creation– iGT submits nomination file in respect of shipper confirmation on

the CSEP

• Issue:– Timing of notification by GT can lead to shipper confirmations

with iGT before set up in Xoserve

• Current arrangements use aggregated values for SSP and individual values for LSP within a CSEP

• Issue:– The LMN for the aggregated shipper SSP portfolio and

individual shipper LSP is not efficient

8Key aspect of current arrangements and possible changes with Nexus solution cont.

• For SSP sites within a CSEP a Shipper “bulk” confirms with the iGT– Process is initiated by the iGT– This process to continue under Nexus for the initial

registration of new meter points• For LSP sites within a CSEP shipper confirms at meter

installation• The Nexus solution will be to hold every supply point at

individual MPRN level
